The author investigates claims that VictoriaMetrics achieves 3-4x better compression than Prometheus-based solutions like Thanos and Cortex.

Background
VictoriaMetrics is a popular time-series database often compared to Prometheus for monitoring workloads. This article stems from a PromCon 2019 discussion about compression differences between these systems.
